This invention relates to a device for cleaning pen points of the typethat is used in writing, drafting, drawing or similar arts.

An object of the invention is to provide a device of this characterhaving two rotating interengaging members which are adapted to receivethe pen point therebetween, and clean all excess fluid from the penpoint as it is engaged and disengaged from the members.

Another object of the invention is to provide a device of this characterthat is attractive in design and is equipped with means for holding thepen point after it has been cleaned.

With the above and other objects and advantages in view, the inventionconsists of the novel details of construction, arrangement andcombination of parts more fully hereinafter described, claimed andillustrated in the accompanying drawings in which:

Figure 1 is a top plan view of an embodiment of the invention;

Figure 2 is an elevational peripheral edge view of the device;

Figure 3 is a sectional view on the line 3-3 of Figure 1;

Figure 4 is a sectional view on the line 44 of Figure 1;

Figure 5 is a detailed elevational view of the pen cleaning mechanismwith the base broken away and Figure 6 is a sectional view on the line66 of Figure 5.

Referring more in detail to the drawings, the pen point cleaner assemblyembodying the invention is generally designated by the reference numeralI0. The assembly I comprises a circular base II having an ornamentalmarginal edge I2 and a circular recess I3 in the center thereof. Formedon the base in upstanding re- 7 lation thereto is the ring shaped flangeI4 which is externally threaded at to engage the internal threads I6 ofthe disk shaped top or cover IT. The marginal edge I8 of the top orcover I! is ornamented to conform or harmonize with the ornamental edgeI2 of the base II.

Mounted on the upper surface of the top or cover IT is an ornamentalblock I9 which, as shown, is substantially elliptical in shape, or itmay be any shape desired. The center of the block I9 is provided with anopening 20 which is adapted to receive a pen point as shown by dottedlines in Figure 4.

Fasteners 2| and 2| are used to retain the block on the top or cover IT,and passing through the top or cover I1, the heads of the'fasteners 2Claims. (Cl. 120-108) are exposed on the undersurface of the top or Cover.

The fastener 2 I, by means of its head, retains a.

spring catch 22, while the head of the fastener 2| retains the keeper 23in place.

The catch 22 and keeper 23 are adapted to removably engage thehorizontally extending rim flange 24 of the rectangular shaped frame 25.The frame, at one end, has a short pin shaft 26 rotatably mounted in thesides of the frame, transversely thereof, and cotter pins 28 in theshaft are positioned on opposite sides of the roller 29 to fix theroller on the shaft 26. The pins 28 engage the washers 3U abutting thesides of the roller 29 and the roller 29 is provided with a curved face3|. The curved face 3| of the roller 29 engages the annular groove 32formed in the face of the roller 33, and both rollers are made of an inkabsorbent material.

The roller 33 is fixed to the pin shaft 34 by cotter pins 35 in theshaft and washers 36 are placed in contact with the sides of the roller33.

Due to the soft material from which the rollers are made, the washersare used to prevent the cotter keys from wearing into the sides of therollers to permit the rollers to become loosened on their respectiveshafts.

The shaft 34 is rotatably mounted transversely of the frame 25 in theelongated slots 31 formed in the sides thereof. This mounting isprovided so that a pen point can be inserted between the rollers, aswill be later described. Loosely mounted on the ends of the shaft 34 isthe yoke 38 on which is formed the apertured ear 29. The ear 39 isadapted to receive one end of the compression spring 40, the other endof which is received in the apertured ear 4| formed on one end of theframe 25. Thus the compression of the spring 49 urges the yoke towardthe end of the frame on which the ear 4| is formed, and the yoke, inturn, urges the roller 33 into engagement with the roller 29.

Thus when a pen point is inserted between the rollers, the rollers willseparate sufficiently to allow the pen point to be receivedtherebetween, while at the same time engaging the pen point to clean thepoint of all excess fluid thereon.

Secured to the upper surface of the top or cover IT, by any well knownfastening means, is a holder 42 of conventional, yet attractive, design,which is adapted to hold the pen point when inserted in a pen holder inthe customary manner.

There has thus been provided a pen point cleaner which is attractive indesign and will effectively clean a pen point when the pen point ispositioned between the rollers, as previously described.

The frame 25 and its component parts being made removable, can bereplaced when the rollers are useless or the rollers only may bereplaced as desired.

It is believed that from the foregoing description, the construction andoperation of the device will be apparent to those skilled in the art,

and it is to be understood that changes in the minor details ofconstruction may be resorted to,

provided they fall within the spirit of the invention and the scope ofthe appended claims.-

Having thus described the invention, what is claimed as new and desiredtobe secured by'Le't ters Patent is:

1. A device of the character described; comprising an ornamental base,an ornamental cover secured to said base, an opening in said covertoreceive a pen point, a rectangular shaped frame mounted on the coverbelow the o ening, said frame having alined openings in the sidesthereof andelongated aliriedslots thesicles' thereof spaced from eachother in parallel relation to each other, a Shaft join nailed intne'e'enih s; and a shaft jdl'irf'lalledin the Slots rotatingabscreensmeans'mountedon'the Shafts in the frameon the cover below theopening to clean a pen point when the pen point is inserted into theopening to engage the absorbent means and tensioning means connected tothe shaft in the slots for urging the absorbent means on the shaft intoengagement with the absorbent means on the shaft in the openings.

2. The invention as in claim 1, wherein the absorbent meanscomprises'two rollers, the faces of which are adapted to engage witheach other and at the same time conform in their engagement with theshape of the pen point.
